Why doesn my PS3 (Play Station 3) work with an HDMI cable?
You will first need to tell your PS3 to use the HDMI cable. Connecting the cable and restarting the system should do this. If this fails, connect both the Euro AV cable and the HDMI cable, find the display settings on the system, and select the output as HDMI, once this has been setup, you can disconnect the Euro AV cable. For further help, you should consult the manual supplied.
